    (54) Integrated personal/cellular communications system architecture


    (57) An integrated PCN/DNC system architecture has a switching center (22), coupled to a public switched telephone (PSTN), which selectively transfers signals between the PSTN and a digital cellular network (DCN) or a personal communications network (PCN) which is allocated a portion of the cellular communications band by a local cellular operator. Each PCN subnetwork (20) of the PCN includes several microcells (18) arranged in a multi-dimensional grid, and the allocated cellular channels are divided into sets assigned to columns of the grid. The allocated portion of the cellular spectrum is reused within each PCN subnetwork (20) by assigning the same set to more than one of the columns so that different communications signals can be transferred over the same cellular channels.
